AJAX Deal

Whats the big deal about AJAX.
Agree it does wonders in few ways. But the same POST/GET process occurs as with pageloads. The difference is it happens transparently. But not necessarily quicker . Therefore, developers must be concerned with providing the user visual clues as to what is happening so they don’t think the system is hung on extra long data loads due to network latency, etc
Bottom line :
I wont bet my money on all websites and webpages to use AJAX. May be some pages in my site, you bet YES .
